    Purification and complementary DNA cloning of a receptor for basic fibroblast growth factor (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-07-07
    Description: Basic fibroblast growth factor (bFGF) participates in many processes including early developmental events, angiogenesis, wound healing, and maintenance of neuronal cell viability. A 130-kilodalton protein was isolated on the basis of its ability to specifically bind to bFGF. A complementary DNA clone was isolated with an oligonucleotide probe corresponding to determined amino acid sequences of tryptic peptide fragments of the purified protein. The putative bFGF receptor encoded by this complementary DNA is a transmembrane protein that contains three extracellular immunoglobulin-like domains, an unusual acidic region, and an intracellular tyrosine kinase domain. These domains are arranged in a pattern that is different from that of any growth factor receptor described.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, P L -- Johnson, D E -- Cousens, L S -- Fried, V A -- Williams, L T -- CA 21765/CA/NCI NIH HHS/ -- R01 HL32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 7;245(4913):57-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2544996" target="_blank"〉PubMed〈/a〉

    MacroH2A, a core histone containing a large nonhistone region (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-09-04
    Description: A histone, macroH2A, nearly three times the size of conventional H2A histone, was found in rat liver nucleosomes. Its N-terminal third is 64 percent identical to a full-length mouse H2A. However, it also contains a large nonhistone region. This region has a segment that resembles a leucine zipper, a structure known to be involved in dimerization of some transcription factors. Nucleosomes containing macroH2A may have novel functions, possibly involving interactions with other nuclear proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pehrson, J R -- Fried, V A -- CA 06927/CA/NCI NIH HHS/ -- GM 24019/GM/NIGMS NIH HHS/ -- RR 05539/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1992 Sep 4;257(5075):1398-400.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fox Chase Cancer Center, Institute for Cancer Research, Philadelphia, PA 19111.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1529340" target="_blank"〉PubMed〈/a〉

    Activation-induced ubiquitination of the T cell antigen receptor (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-08-07
    Description: The zeta subunit of the T cell antigen receptor (TCR) exists primarily as a disulfide-linked homodimer. This receptor subunit is important in TCR-mediated signal transduction and is a substrate for a TCR-activated protein tyrosine kinase. The zeta chain was found to undergo ubiquitination in response to receptor engagement. This posttranslational modification occurred in normal T cells and tumor lines. Both nonphosphorylated and phosphorylated zeta molecules were modified, and at least one other TCR subunit, CD3 delta, was also ubiquitinated after activation of the receptor. These findings suggest an expanded role for ubiquitination in transmembrane receptor function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cenciarelli, C -- Hou, D -- Hsu, K C -- Rellahan, B L -- Wiest, D L -- Smith, H T -- Fried, V A -- Weissman, A M -- New York, N.Y. -- Science. 1992 Aug 7;257(5071):795-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Experimental Immunology Branch, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1323144" target="_blank"〉PubMed〈/a〉

    Antibodies to PfSEA-1 block parasite egress from RBCs and protect against malaria infection (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-05-24
    Description: Novel vaccines are urgently needed to reduce the burden of severe malaria. Using a differential whole-proteome screening method, we identified Plasmodium falciparum schizont egress antigen-1 (PfSEA-1), a 244-kilodalton parasite antigen expressed in schizont-infected red blood cells (RBCs). Antibodies to PfSEA-1 decreased parasite replication by arresting schizont rupture, and conditional disruption of PfSEA-1 resulted in a profound parasite replication defect. Vaccination of mice with recombinant Plasmodium berghei PbSEA-1 significantly reduced parasitemia and delayed mortality after lethal challenge with the Plasmodium berghei strain ANKA. Tanzanian children with antibodies to recombinant PfSEA-1A (rPfSEA-1A) did not experience severe malaria, and Kenyan adolescents and adults with antibodies to rPfSEA-1A had significantly lower parasite densities than individuals without these antibodies. By blocking schizont egress, PfSEA-1 may synergize with other vaccines targeting hepatocyte and RBC invasion.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4184151/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4184151/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raj, Dipak K -- Nixon, Christian P -- Nixon, Christina E -- Dvorin, Jeffrey D -- DiPetrillo, Christen G -- Pond-Tor, Sunthorn -- Wu, Hai-Wei -- Jolly, Grant -- Pischel, Lauren -- Lu, Ailin -- Michelow, Ian C -- Cheng, Ling -- Conteh, Solomon -- McDonald, Emily A -- Absalon, Sabrina -- Holte, Sarah E -- Friedman, Jennifer F -- Fried, Michal -- Duffy, Patrick E -- Kurtis, Jonathan D -- 1K08AI100997-01A1/AI/NIAID NIH HHS/ -- DP2 AI112219/AI/NIAID NIH HHS/ -- DP2-AI112219/AI/NIAID NIH HHS/ -- K08 AI100997/AI/NIAID NIH HHS/ -- P20GM103421/GM/NIGMS NIH HHS/ -- P30 AI042853/AI/NIAID NIH HHS/ -- P30AI042853/AI/NIAID NIH HHS/ -- R01 AI102907/AI/NIAID NIH HHS/ -- R01-AI076353/AI/NIAID NIH HHS/ -- R01-AI102907/AI/NIAID NIH HHS/ -- R01-AI52059/AI/NIAID NIH HHS/ -- T32-DA013911/DA/NIDA NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2014 May 23;344(6186):871-7. doi: 10.1126/science.1254417.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for International Health Research, Rhode Island Hospital, The Warren Alpert Medical School of Brown University, Providence, RI 02903, USA. ; Division of Infectious Diseases, Boston Children's Hospital and Harvard Medical School, Boston, MA 02115, USA. ; Center for International Health Research, Rhode Island Hospital, The Warren Alpert Medical School of Brown University, Providence, RI 02903, USA.

    Neurodevelopment. Parasympathetic neurons originate from nerve-associated peripheral glial progenitors (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-06-14
    Description: The peripheral autonomic nervous system reaches far throughout the body and includes neurons of diverse functions, such as sympathetic and parasympathetic. We show that the parasympathetic system in mice--including trunk ganglia and the cranial ciliary, pterygopalatine, lingual, submandibular, and otic ganglia--arise from glial cells in nerves, not neural crest cells. The parasympathetic fate is induced in nerve-associated Schwann cell precursors at distal peripheral sites. We used multicolor Cre-reporter lineage tracing to show that most of these neurons arise from bi-potent progenitors that generate both glia and neurons. This nerve origin places cellular elements for generating parasympathetic neurons in diverse tissues and organs, which may enable wiring of the developing parasympathetic nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dyachuk, Vyacheslav -- Furlan, Alessandro -- Shahidi, Maryam Khatibi -- Giovenco, Marcela -- Kaukua, Nina -- Konstantinidou, Chrysoula -- Pachnis, Vassilis -- Memic, Fatima -- Marklund, Ulrika -- Muller, Thomas -- Birchmeier, Carmen -- Fried, Kaj -- Ernfors, Patrik -- Adameyko, Igor -- MC_U117537087/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Jul 4;345(6192):82-7. doi: 10.1126/science.1253281.

    Glial origin of mesenchymal stem cells in a tooth model system (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-08-01
    Description: Mesenchymal stem cells occupy niches in stromal tissues where they provide sources of cells for specialized mesenchymal derivatives during growth and repair. The origins of mesenchymal stem cells have been the subject of considerable discussion, and current consensus holds that perivascular cells form mesenchymal stem cells in most tissues. The continuously growing mouse incisor tooth offers an excellent model to address the origin of mesenchymal stem cells. These stem cells dwell in a niche at the tooth apex where they produce a variety of differentiated derivatives. Cells constituting the tooth are mostly derived from two embryonic sources: neural crest ectomesenchyme and ectodermal epithelium. It has been thought for decades that the dental mesenchymal stem cells giving rise to pulp cells and odontoblasts derive from neural crest cells after their migration in the early head and formation of ectomesenchymal tissue. Here we show that a significant population of mesenchymal stem cells during development, self-renewal and repair of a tooth are derived from peripheral nerve-associated glia. Glial cells generate multipotent mesenchymal stem cells that produce pulp cells and odontoblasts. By combining a clonal colour-coding technique with tracing of peripheral glia, we provide new insights into the dynamics of tooth organogenesis and growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaukua, Nina -- Shahidi, Maryam Khatibi -- Konstantinidou, Chrysoula -- Dyachuk, Vyacheslav -- Kaucka, Marketa -- Furlan, Alessandro -- An, Zhengwen -- Wang, Longlong -- Hultman, Isabell -- Ahrlund-Richter, Lars -- Blom, Hans -- Brismar, Hjalmar -- Lopes, Natalia Assaife -- Pachnis, Vassilis -- Suter, Ueli -- Clevers, Hans -- Thesleff, Irma -- Sharpe, Paul -- Ernfors, Patrik -- Fried, Kaj -- Adameyko, Igor -- G0901599/Medical Research Council/United Kingdom -- MC_U117537087/Medical Research Council/United Kingdom -- England -- Nature. 2014 Sep 25;513(7519):551-4. doi: 10.1038/nature13536.

    DNA-dependent kinase (p350) as a candidate gene for the murine SCID defect (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-02-24
    Description: Severe combined immunodeficient (SCID) mice are deficient in a recombination process utilized in both DNA double-strand break repair and in V(D)J recombination. The phenotype of these mice involves both cellular hypersensitivity to ionizing radiation and a lack of B and T cell immunity. The catalytic subunit of DNA-dependent protein kinase, p350, was identified as a strong candidate for the murine gene SCID. Both p350 and a gene complementing the SCID defect colocalize to human chromosome 8q11. Chromosomal fragments expressing p350 complement the SCID phenotype, and p350 protein levels are greatly reduced in cells derived from SCID mice compared to cells from wild-type mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kirchgessner, C U -- Patil, C K -- Evans, J W -- Cuomo, C A -- Fried, L M -- Carter, T -- Oettinger, M A -- Brown, J M -- CA 15201/CA/NCI NIH HHS/ -- CA 37761/CA/NCI NIH HHS/ -- GM48026/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Feb 24;267(5201):1178-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Radiation Oncology, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7855601" target="_blank"〉PubMed〈/a〉

    Cell surface molecule associated with lymphocyte homing is a ubiquitinated branched-chain glycoprotein (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-21
    Description: Partial amino acid sequence analysis of a purified lymphocyte homing receptor demonstrates the presence of two amino termini, one of which corresponds precisely to the amino terminus of ubiquitin. This observation extends the province of this conserved polypeptide to the cell surface and leads to a proposed model of the receptor complex as a core polypeptide modified by glycosylation and ubiquitination. Independent antibodies to ubiquitin serve to identify additional cell surface species, an indication that ubiquitination of cell surface proteins may be more general. It is proposed that functional binding of lymphocytes to lymph node high endothelial venules might involve the ubiquitinated region of the receptor; if true, cell surface ubiquitin could play a more general role in cell-cell interaction and adhesion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Siegelman, M -- Bond, M W -- Gallatin, W M -- St John, T -- Smith, H T -- Fried, V A -- Weissman, I L -- AI 19512/AI/NIAID NIH HHS/ -- CA 09151/CA/NCI NIH HHS/ -- GM 31461/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 21;231(4740):823-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003913" target="_blank"〉PubMed〈/a〉

    Expression cloning of a lymphocyte homing receptor cDNA: ubiquitin is the reactive species (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-21
    Description: The lymphocyte cell surface receptor for the high endothelial venules (HEV's) of peripheral lymph nodes is specifically recognized by the monoclonal antibody MEL-14. Three independent complementary DNA (cDNA) clones, each of which encodes the protein ubiquitin, were detected by virtue of the expression of the MEL-14 antigenic determinant on cDNA-beta-galactosidase bacterial fusion proteins. The antigenic determinant defined by MEL-14 resides in the carboxyl terminal 13-amino-acid proteolytic peptide of ubiquitin, but is undetected in intact undenatured ubiquitin and other cellular ubiquitinated proteins. Antisera and monoclonal antibodies to ubiquitin determinants bind to the surface of both HEV-receptor positive and negative cell lines. The MEL-14-identified cDNA clones hydridize to RNA transcripts that encode tandemly repeated ubiquitins. Sequence analysis of these polyubiquitin cDNA's does not identify a leader sequence for export to the cell surface. The expression of the MEL-14 epitope of ubiquitin depends upon its local environment. The steady-state levels of expression of the ubiquitin messenger RNA's do not correlate with either the tissue derivation of the RNA or the expression of the lymphocyte HEV receptor. Regulation of the expression of the HEV receptor is not likely to reflect the transcriptional control of ubiquitin genes, but rather to reflect control of the expression of the HEV core polypeptide or its level or form of ubiquitination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉St John, T -- Gallatin, W M -- Siegelman, M -- Smith, H T -- Fried, V A -- Weissman, I L -- AI19512/AI/NIAID NIH HHS/ -- CA 09151/CA/NCI NIH HHS/ -- GM 31461/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 21;231(4740):845-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003914" target="_blank"〉PubMed〈/a〉
